305-016-556-201

Edgeboard Connectors Overview

The EDAC Inc. 305-016-556-201 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 16 positions with a contact spacing of 0.156 inches (3.96 mm). The connector supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and accommodates board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). It utilizes gold-plated copper alloy contacts and offers a current rating of 5 A. The housing is green thermoplastic, and it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure mating with specified card edge PCBs
• Gold-plated copper alloy contacts ensure reliable electrical performance and corrosion resistance
• Low-profile insulator body constructed from thermoplastic material for compact integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board dimensions
• Test and measurement devices needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify that the target application requires a dual-edge connector configuration rather than single-edge variants within the same series. Confirm compatibility with the specific PCB thickness range of 1.37 mm to 1.78 mm to ensure proper mechanical retention. Check for RoHS3 compliance requirements if environmental regulations apply to the final assembly. Ensure soldering processes align with the thermal characteristics of the thermoplastic housing.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface is necessary for the specific PCB design. The 3.96 mm pitch dictates the trace layout on the mating board, which must be verified during the schematic phase. Consider the 5 A current rating against the total load requirements of the connected circuitry. The straight mounting style and through-hole termination method should match the available board space and manufacturing capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which provides various configurations of card edge connectors. The series includes options with different position counts and row spacings to accommodate diverse board sizes. The 305-016-556-201 specifically addresses needs for smaller form-factor dual-edge connections while maintaining the structural integrity and electrical standards established by the broader product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with identical 16-position dual-edge specifications but different housing colors or minor packaging variations. Cross-manufacturer replacements require strict verification of the 3.96 mm pitch and 1.57 mm board thickness tolerance to prevent mechanical misalignment.
